Kittimas place is excellently located among the river with amazing views over the city.
I stayed for a month while working from the flat and everything was great, the internet was perfect the whole time.
It's not a far walk to lots of shops, food places and a bit further away is a large mall that has everything you need. It is a longer walk to central Bangkok but a 90p grab will get you right there in no time.
Everything was as described and Kittima was very easy to contact and talk with. I would highly recommend it!
